Upon reasonable prior notice and without disruption to Amgen’s business, such records of Amgen and its Affiliates shall be made available during regular business hours for a period of [***] from the end of the Calendar Year to which they pertain for examination, and not more often than once each Calendar Year, by an independent certified public accountant selected by Arrowhead and reasonably acceptable to Amgen, for the sole purpose of and only to the extent necessary for verifying the accuracy of the financial reports furnished by Amgen pursuant to this Article 9.  Such independent accountant shall disclose to Arrowhead only the amounts that such independent accountant believes to be due and payable hereunder to Arrowhead, details concerning any discrepancy from the amount paid and the amount due, and shall disclose no other information revealed in such audit.  The records for any particular Calendar Year shall only be subject to one (1) audit hereunder.  Any and all records examined by such independent accountant shall be deemed Amgen’s Confidential Information which may not be disclosed by such independent accountant to any Third Party, and Amgen may require such independent accountant to enter into an appropriate written agreement obligating it to be bound by obligations of confidentiality and restrictions on use of such Confidential Information that are no less protective than those set forth in Article 13.  If, as a result of any inspection of the books and records of Amgen, it is shown that payments under this Agreement were less than the amount which should have been paid, then Amgen shall make all payments required to be made from the original due date to eliminate any discrepancy revealed by such inspection within [***].  If, as a result of any inspection of the books and records of Amgen, it is shown that payments under this Agreement were more than the amount which should have been paid, then Arrowhead shall, at Amgen’s election, either make all payments required to be made to eliminate any discrepancy revealed by such inspection within [***] or credit such amounts to Amgen against future payments.  Arrowhead shall pay for such audits, except that in the event that the audited amounts were underpaid by Amgen by more than [***] of the

undisputed amounts that should have been paid during the period in question as per the audit, Amgen shall pay the costs of the audit.

9.13Taxes. 

(a)Taxes on Income.  Each Party shall be solely responsible for the payment of all taxes imposed on its share of income arising directly or indirectly from the efforts of the Parties under this Agreement.

(b)Cooperation.  The Parties agree to cooperate with one another and use reasonable efforts to reduce or eliminate tax withholding or similar obligations in respect of royalties, milestone payments, and other payments made by Amgen to Arrowhead under this Agreement.  To the extent Amgen is required under the Internal Revenue Code of 1986, as amended (the “Code”), or any other tax Laws to deduct and withhold taxes on any payment to Arrowhead, Amgen shall pay the amounts of such taxes to the proper Governmental Authority in a timely manner and promptly transmit to Arrowhead an official tax certificate or other evidence of such withholding sufficient to enable Arrowhead to claim such payment of taxes.  Except as otherwise provided in Section 9.13(c), if any taxes are so deducted or withheld, such deducted or withheld amounts shall be treated for all purposes of this Agreement as having been paid to Arrowhead. Upon Amgen’s reasonable request, Arrowhead shall provide Amgen any tax forms (including Internal Revenue Service Form W-8BEN or W-8ECI or other applicable Internal Revenue Service Form) that may be reasonably necessary in order for Amgen to determine whether to withhold tax on any such payments or to withhold tax on such payments at a reduced rate under the Code or any other tax Laws, including any applicable bilateral income tax treaty.  Amgen shall give reasonable support so that any withholding tax or value added tax may be minimized or avoided to the extent permitted under the applicable Laws and treaties.  Each Party shall provide the other with reasonable assistance to enable the recovery, as permitted by applicable Laws, of withholding taxes, value added taxes, or similar obligations resulting from payments made under this Agreement, such recovery to be for the benefit of the Party bearing such withholding tax or value added tax.  Amgen shall require its sublicensees in the Territory to cooperate with Arrowhead in a manner consistent with this Section 9.13(b).

(c)Taxes Resulting From Amgen Action.  If Amgen is required to make a payment to Arrowhead that is subject to increased deduction or withholding of tax as a result of any willful action by Amgen, such as an assignment or sublicense by Amgen, or any failure on the part of Amgen to comply with applicable Laws or filing or record retention requirements (an “Amgen Withholding Tax Action”), then the sum payable by Amgen (in respect of which such increased deduction or withholding is required to be made) shall be increased to the extent necessary to ensure that Arrowhead receives a sum equal to the sum which it would have received had no such Amgen Withholding Tax Action occurred.  Notwithstanding the foregoing, any assignment or sublicense by Amgen that is agreed or consented to by Arrowhead in advance in writing shall not constitute an Amgen Withholding Tax Action.  To the extent that Arrowhead actually realizes a tax benefit in any jurisdiction as a result of any such withholding taxes paid by Amgen pursuant to this Section 9.13(c), Arrowhead shall cooperate with Amgen to convey the additional tax benefit, if possible, to Amgen.

INTELLECTUAL PROPERTY MATTERS

10.1Inventions.  Any inventions, whether or not patentable, and whether (a) invented solely by a Party’s own employees, agents, consultants, or independent contractors (including any partner, joint venturer, licensee, sublicensee or similar arrangement) or (b) invented by a Party’s own employees, agents, consultants, or independent contractors jointly with employees, agents, consultants, or independent contractors of the other Party, in each case in the course of conducting a Party’s activities under this Agreement (including the Development, Manufacture or Commercialization of the Licensed Compounds and the Licensed Products), together with all intellectual property rights therein, shall be referred to herein as an “Invention”.  Inventorship shall be determined in accordance with U.S. patent laws (without reference to any conflict of law principles).

10.2Ownership.  

(a)Except as otherwise expressly provided in this Agreement, (i) if an Invention is solely invented by one or more employees, agents, consultants, subcontractors or independent contractors of a Party, such Invention, and any and all intellectual property rights therein, shall be solely owned by such Party; and (ii) if an Invention is jointly invented by one or more employees, agents, consultants, subcontractors or independent contractors of each Party, such Invention (a “Joint Invention”), and each Patent claiming such Joint Invention (each, a “Joint Patent”) and other intellectual property rights in such Joint Invention (such intellectual property rights, together with any such Joint Patent, “Joint IPR”), shall be jointly owned by the Parties.  Subject to the terms of this Agreement and except as otherwise licensed to the other Party under this Agreement, and subject to any other intellectual property owned by the Parties, each Party shall be entitled to practice and exploit the Joint Inventions and Joint IPR, subject to the licenses granted under Article 4, without the duty of accounting, paying a share of the proceeds to, or seeking consent from the other Party, and each Party hereby waives any right it may have under the laws of any jurisdiction to require such accounting, payment or consent; provided, however, that for any Joint Patent that, but for Amgen’s inventive contribution, would be an Arrowhead Platform Patent, Amgen’s rights to practice and exploit the Joint Patent shall be limited to its use with a RNAi Molecule directed toward the Collaboration Target, Licensed Compounds, and Licensed Products.  Each Party agrees to be named as a party, if necessary, to bring or maintain a lawsuit involving a Joint Invention or Joint IPR.  

(b)Each Party shall notify the other Party promptly after developing any Invention of which the other Party is the sole owner.  Each Party shall assign and hereby assigns to the other Party its entire right, title and interest in and to such Inventions and the Patents and other intellectual property rights therein as needed to implement the ownership of the Patents in accordance with the provisions of Section 10.2(a).  

(c)Nothing in this Agreement shall obligate either Party to transfer any ownership interest in any Patents or other intellectual property rights of such Party existing on the Effective Date (“Background IP”).

10.3Prosecution of Patents.

(a)Arrowhead Patents.

(i)Subject to Section 10.3(a)(ii) and (iii), as between the Parties, Arrowhead shall have the sole right to prepare, file, prosecute and maintain all Arrowhead Patents (A) listed as “Platform Patents” on Exhibits C and D or (B) filed after the Effective Date and during the Term, except for any Arrowhead Product Patents as defined in Section 10.3(a)(ii), in each case including all Patents that claim priority, directly or indirectly, from such Patents; and any Patent from which such Patents claim priority, directly or indirectly (collectively, the “Arrowhead Platform Patents”), at Arrowhead’s cost and expense.  For clarity, all Arrowhead Background IP Controlled by Arrowhead or its Affiliates as of the Effective Date that is or becomes the subject of patent claims are included as Arrowhead Platform Patents.  On a Calendar Quarter basis, Arrowhead shall update Amgen on the status of the prosecution and maintenance of all Arrowhead Platform Patents and shall provide Amgen with copies of material filings with and communications from patent authorities with respect to such Patents to the extent applicable to Licensed Compounds or Licensed Products.  Arrowhead shall respond to all reasonable requests of Amgen for additional Information with respect to all such prosecution and maintenance efforts.  Arrowhead agrees to discuss and consider in good faith any recommendations of Amgen toward the objective of optimizing overall patent protection for Licensed Compounds (during the Term) and Licensed Products (during the Term).  If Arrowhead decides to cease the prosecution or maintenance of all claims in an Arrowhead Platform Patent that claims the Development, Manufacture or Commercialization of a Licensed Compound or Licensed Product in the Territory, it shall notify Amgen in writing sufficiently in advance so that Amgen may, at its discretion, assume the responsibility for the prosecution or maintenance of such Arrowhead Platform Patent to the extent claiming the Development, Manufacture or Commercialization of a Licensed Compound or Licensed Product in the Territory, at Amgen’s cost and expense.  If Amgen assumes such responsibility in a jurisdiction, then no such claim shall be deemed a Valid Claim in such jurisdiction.  

(ii)As between the Parties, (x) prior to the exercise of the Option, Arrowhead shall have the first right to prepare, file, prosecute and maintain all Arrowhead Patents filed during the Term and having claims solely directed to compositions of matter comprising the nucleotide sequence and/or the modification pattern of Licensed Compounds or Licensed Products or methods of using or making Licensed Compounds or Licensed Products (collectively, the “Arrowhead Product Patents”) in the Territory, at Arrowhead’s cost and expense and (y) from and after the exercise of the Option, Amgen shall have the first right to prepare, file, prosecute and maintain all Arrowhead Product Patents in the Territory, at Amgen’s cost and expense.  The prosecuting Party shall reasonably inform and consult with the other Party, and shall take the other Party’s comments into good faith consideration, with respect to the preparation, prosecution and maintenance of such Arrowhead Product Patents.  Promptly following exercise of the Option, Arrowhead shall transfer control of the Arrowhead Product Patents to Amgen.  The prosecuting Party shall provide to the other Party copies of any correspondence relating to the filing, prosecution or maintenance of such Arrowhead Product Patents reasonably in advance of their being filed or promptly upon their being received, including draft filings, reasonably in advance of their being filed, so that the other Party can comment and provide input with respect to such draft filings.  The prosecuting Party agrees to discuss and consider in good faith any changes 

27.

reasonably requested by the other Party to such correspondence, including draft filings, as promptly as practicable upon their being received, toward the objective of optimizing overall patent protection for Licensed Compounds or the Licensed Products.  If the prosecuting Party decides to cease the prosecution or maintenance of an Arrowhead Product Patent, it shall notify the other Party in writing sufficiently in advance so that the other Party may, at its discretion, assume the responsibility for the prosecution or maintenance of such Arrowhead Product Patents at such other Party’s cost and expense.  Notwithstanding the foregoing, while Arrowhead is the prosecuting Party pursuant to clause (x) above, Arrowhead shall not file any Patent application with respect to an Arrowhead Product Patent without the prior written consent of Amgen, not to be unreasonably withheld, conditioned or delayed.    

(iii)Following the Effective Date, the Parties shall meet and discuss the extent to which it is feasible to allocate certain claims in the Arrowhead Platform Patents to the Arrowhead Product Patents.  At the reasonable request of Amgen, Arrowhead shall make such filings as the Parties reasonably agree to allocate claims solely claiming Licensed Compounds and/or Licensed Products in any and all fields to the Arrowhead Product Patents.  The Parties shall equally share in the costs associated with such actions reasonably requested by Amgen. 

(b)Joint Patents.  Amgen shall have the first right to prepare, file, prosecute and maintain all Joint Patents in the Territory, at Amgen’s cost and expense. Amgen shall reasonably inform and consult with Arrowhead, and shall take such other Arrowhead’s comments into good faith consideration, with respect to the preparation, prosecution and maintenance of such Joint Patents.  Amgen shall provide to Arrowhead copies of any correspondence relating to the filing, prosecution or maintenance of such Joint Patents reasonably in advance of their being filed or promptly upon their being received, including draft filings, reasonably in advance of their being filed so that Arrowhead can comment and provide input with respect to such draft filings.  Amgen agrees to discuss and consider in good faith any changes reasonably requested by Arrowhead to such correspondence, including draft filings, promptly upon their being received, toward the objective of optimizing overall patent protection for Licensed Compounds and the Licensed Product.  If Amgen decides to cease the prosecution or maintenance of a Joint Patent, it shall notify Arrowhead in writing sufficiently in advance so that Arrowhead may, at its discretion, assume the responsibility for the prosecution or maintenance of such Joint Patent at Arrowhead’s cost and expense.  

(c)Cooperation.  Each Party shall provide the other Party all reasonable assistance and cooperation, at the other Party’s request and expense, in the patent prosecution efforts as provided above in this Section 10.3, including providing any necessary powers of attorney and executing any other required documents or instruments for such prosecution.  Each Party shall execute and deliver to the other assignments with respect to any Patents, including Joint Inventions, as applicable, in a mutually agreeable form and will take whatever actions reasonably necessary (including the appointment of the other Party as its attorney in fact solely to make such assignment) to effect such assignment, in accordance with the ownership provisions provided above in Section 10.2.  The prosecuting Party under this Section 10.3 agrees to conduct such prosecution toward the objective of optimizing overall patent protection for Licensed Compounds and Licensed Products.

10.4Enforcement of Arrowhead Patents and Joint Patents.

(a)Notification.  If either Party becomes aware of any existing or threatened infringement of Arrowhead Patents or Joint Patents with respect to Third Party products involving RNAi Molecules in any and all fields in the Territory, which infringing activity involves the using, making, importing, offering for sale or selling RNAi Molecules directed to the Collaboration Target, Licensed Compounds or Licensed Products, in each case in any and all fields and in the Territory, or any such Arrowhead Patent or Joint Patent is challenged in any action or proceeding to the extent directly relating to RNAi Molecules directed to the Collaboration Target, Licensed Compounds or Licensed Products, in each case in any field  and in the Territory (other than any oppositions, cancellations, interferences, reissue proceedings or reexaminations, which are addressed in Section 10.7) (a “Product Infringement”), it shall promptly notify the other Party in writing to that effect and the Parties will consult with each other regarding any actions to be taken with respect to such Product Infringement.  Each Party shall share with the other Party all Information available to it regarding such alleged Product Infringement.

(b)Enforcement.

(i)Arrowhead shall have the first right, but not the obligation, to bring an appropriate suit or other action against any person or entity engaged in a Product Infringement of the Arrowhead Platform Patents.  Arrowhead shall keep Amgen regularly informed of the status and progress of such enforcement efforts, shall reasonably consider Amgen’s comments on any such efforts, and shall seek consent of Amgen in any important aspects of such enforcement, including determination of litigation strategy and filing of material papers to the competent court, which consent shall not be unreasonably withheld or delayed.  In addition, Arrowhead shall provide Amgen with drafts of all material papers to be filed with the court and shall in good faith incorporate all reasonable comments thereto by Amgen before filing such papers.  Amgen shall provide to Arrowhead reasonable assistance in such enforcement pursuant to this subsection (b)(i), at Arrowhead’s request and expense, including joining such action as a party plaintiff if required by applicable Laws to pursue such action. 

(ii)If Arrowhead elects not to commence a suit to enforce the applicable Arrowhead Platform Patents or settle or otherwise secure the abatement of such Product Infringement, then Amgen shall have the right, but not the obligation, to commence a suit or take action to enforce such Arrowhead Platform Patents against such Product Infringement in any and all fields in the Territory at its own cost and expense.  In such event, promptly after Arrowhead’s notice to Amgen that it does not elect to enforce such Arrowhead Platform Patents, the Parties shall meet to discuss in good faith the strategy for enforcing such Arrowhead Platform Patents.  Amgen acknowledges and agrees that the Arrowhead Platform Patents may be licensed to Third Parties who have rights with respect to the enforcement of such Patents, and that Amgen’s rights to conduct any enforcement activities are subject to such rights.  In any event, Arrowhead shall have the right to consult with such Third Party licensees prior to making any decisions with respect to enforcement activities under this Section 10.4(b)(ii).  In addition, Amgen shall provide Arrowhead with drafts of all material papers to be filed with the court and shall incorporate all reasonable comments thereto by Arrowhead before filing such papers.  Arrowhead shall be entitled to separate representation in such matter by counsel of its own choice and at its own expense.

(iii)Amgen shall have the first right, but not the obligation, to bring and control an appropriate suit or other action against any person or entity engaged in a Product Infringement of the Arrowhead Product Patents or Joint Patents, in its own name and entirely under its own direction and control, subject to the following.  Amgen shall keep Arrowhead regularly informed of the status and progress of such enforcement efforts.  Amgen shall consult with Arrowhead and take any Arrowhead comments into good faith consideration with respect to the infringement, claim construction, or defense of the validity or enforceability of any claim in any Arrowhead Product Patent or Joint Patent.  In addition, Amgen shall provide Arrowhead with drafts of all material papers to be filed with the court and shall incorporate all reasonable comments thereto by Arrowhead before filing such papers.  Arrowhead shall provide to Amgen reasonable assistance in such enforcement pursuant to this Section 10.4(b)(iii), at Amgen’s request and expense, including joining such action as a party plaintiff if requested by Amgen or required by applicable Laws to pursue such action.  Arrowhead shall be entitled to separate representation in such matter by counsel of its own choice and at its own expense.

(iv)If Amgen elects not to settle, or bring any action or proceeding as described in Section 10.4(b)(iii), then it will notify Arrowhead thereof and Arrowhead may bring such suit or other action against any person or entity engaged in a Product Infringement of the Arrowhead Product Patents or Joint Patents, in its own name and entirely under its own direction and control, subject to the following.  Arrowhead shall consult with Amgen and take any Amgen comments into good faith consideration with respect to the infringement, claim construction, or defense of the validity or enforceability of any claim in any Arrowhead Product Patent or Joint Patent.  Amgen shall provide to Arrowhead reasonable assistance in such enforcement pursuant to this Section 10.4(b)(iv), at Arrowhead’s request and expense, including joining such action as a party plaintiff if requested by Arrowhead or required by applicable Laws to pursue such action.  Amgen shall have the right to participate and be represented in any such suit by its own counsel at its own expense with respect to a Product Infringement.  No settlement of any such action or proceeding which restricts the scope, or adversely affects the enforceability, of any Arrowhead Product Patent or Joint Patent, or imposes on Amgen any restrictions, obligations or other liabilities, shall be entered into by Arrowhead without the prior written consent of Amgen, which consent shall not be unreasonably withheld, conditioned, or delayed.  Arrowhead shall not knowingly take any action during such litigation of any Arrowhead Product Patent or Joint Patent that would materially and adversely affect them, without Amgen’s prior written consent, which shall not be unreasonably withheld, delayed, or conditioned.  Notwithstanding the foregoing, Arrowhead will not have the right to enforce or settle any such action or proceeding if Amgen has a good faith belief that enforcement of such Arrowhead Product Patent or Joint Patent in such circumstances could unreasonably jeopardize the rights licensed to Amgen under such Patent. 

(v)Notwithstanding Section 10.4(b)(ii) or (iv), if a Third Party submits an application to the appropriate Regulatory Authority for approval to sell a drug product, and supports the application with any safety, efficacy, or other data that either Party has generated in Developing a Licensed Compound or Licensed Product, then the following will apply:

(1)if a Party receives from the Third Party a notice alleging that the Third Party’s manufacture, use, or sale of the drug product does not infringe an Arrowhead Patent, or that such Patent is invalid or unenforceable (such as a certification under 21 U.S.C. §§ 355(b)(2)(A)(iv) or 355(j)(2)(A)(vii)(IV), 21 C.F.R. §§ 314.94 or 314.95, 42 U.S.C. § 262(l), or 

30.

. Confidential



 

under any other law anywhere in the world that by its effect permits a Third Party to support its application for approval with any safety, efficacy, or other data generated in Developing a Licensed Compound or Licensed Product), then the Party receiving the notice will provide it to the other Party via facsimile and overnight courier as soon as practicable and at least within five (5) days after receiving the notice.

(2)Arrowhead will have the first right, but not the obligation, to institute and control (where Arrowhead is a plaintiff) or defend and control (where Arrowhead is a defendant) an action before any government or private tribunal against the Third Party concerning the infringement, validity, and enforceability of any Arrowhead Platform Patent and to settle any claims in connection with such Patents.  Amgen will have the first right, but not the obligation, to institute and control (where Amgen is a plaintiff) or defend and control (where Amgen is a defendant) an action before any government or private tribunal against the Third Party concerning the infringement, validity, and enforceability of any Arrowhead Product Patent and to settle any claims in connection with such Patents.  If the applicable Party decides not to institute (or defend, as applicable) such action, such Party will give notice to the other Party of its decision within twenty (20) days of the deadline for initiating the action (or, if such Party is defending the action, within twenty (20) days of any deadline required to maintain the action), upon receipt of which the other Party may institute (or defend, as applicable) and control such action.  Each Party will cooperate fully with the other Party in such actions and will provide reasonable assistance (including making available to such other Party documents possessed by such Party that are reasonably required by such other Party and making available personnel for interviews and testimony) in any actions undertaken in accordance with this Section 10.4(b)(v).  At the controlling Party’s request, the other Party agrees to join any such action, or, in the case of Arrowhead, to use reasonable efforts to cause any Third Party licensor under any license agreement between Arrowhead and such Third Party pursuant to which Arrowhead has obtained rights to any Arrowhead Licensed Technology, including the agreements set forth on Exhibit E, to join any such action, for the purpose of establishing standing.  Each Party will have the right to approve any settlement under Section 10.4(b)(v) that would adversely affect the Arrowhead Patents or result in any liability, restriction, obligation or admission on behalf of such Party, such approval not to be unreasonably withheld, conditioned, or delayed.  Any recovery, by settlement or otherwise, realized as a result of such litigation will be allocated in accordance with Section 10.4(d).

(c)Settlement.  Neither Party shall settle any claim, suit or action that it brought under Section 10.4(b) without the prior written consent of the other Party, not to be unreasonably withheld, delayed, or conditioned.  Nothing in this Article 10 shall require such other Party to consent to any settlement that is reasonably anticipated by such other Party to have a material and adverse impact upon any Arrowhead Patents or Joint Patents.

(d)Expenses and Recoveries.  The enforcing Party bringing a claim, suit or action under Section 10.4(b) shall be solely responsible for any expenses incurred by such Party as a result of such claim, suit or action.  If such Party recovers monetary damages in such claim, suit or action, such recovery shall first be allocated to the reimbursement of any expenses incurred by the Parties in such litigation (including, for this purpose, a reasonable allocation of expenses of internal counsel).  If such recovery is insufficient to cover all such costs and expenses of both Parties, it shall be shared in proportion to the total of such costs and expenses incurred by each 

31.

Party.  If after such reimbursement any funds remain from such damages or other sums recovered, if Amgen brought such suit, such remaining funds shall [***].

(e)Infringement Other Than a Product Infringement.  For any and all infringement of any Arrowhead Patents or Joint Patents other than a Product Infringement, as between the Parties, (i) Arrowhead shall have the sole and exclusive right to bring an appropriate suit or other action against any person or entity engaged in such other infringement of an Arrowhead Patent, in its sole discretion, and shall bear all related expenses and retain all related recoveries, and (ii) each Party shall have the right to bring an appropriate suit or other action against any person or entity engaged in such other infringement of a Joint Patent, in its sole discretion, and shall bear all related expenses and retain all related recoveries, and the other Party shall provide reasonable assistance in such enforcement action, including joining such action as a party plaintiff if required by applicable Laws to pursue such action, at the request and expense of the Party bringing the suit or action.  

10.5Patents Licensed From Third Parties.  Each Party’s rights under this Article 10 with respect to the prosecution, maintenance and enforcement of any Arrowhead Patent that is licensed by Arrowhead from a Third Party shall be subject to the rights of such Third Party to prosecute, maintain and enforce such Patent.

10.6Infringement of Third Party Rights in the Territory.  If any Licensed Compound or Licensed Product used or sold by Amgen, its Affiliates or sublicensees becomes the subject of a Third Party’s claim or assertion of infringement of a Patent granted by a jurisdiction within the Territory, Amgen shall promptly notify Arrowhead and the Parties shall agree on and enter into a “common interest agreement” wherein the Parties agree to their shared, mutual interest in the outcome of such potential dispute, and thereafter, the Parties shall promptly meet to consider the claim or assertion and the appropriate course of action.  Amgen shall be solely responsible for the defense of any such infringement claims, provided that Amgen shall provide to Arrowhead the ability to join such action, at Arrowhead’s request and expense, to pursue such action in which a patent asserted by a Third Party under this Section 10.6, claims (a) the composition of matter or use, sale, offer for sale, or importation in any and all fields of any Licensed Compound or Licensed Product or (b) the manufacture of any such Licensed Compound or Licensed Product using the process employed by Arrowhead as of the Effective Date (any such patent, “Subject Patent”).  To the extent directly related to the Subject Patent, Amgen shall keep Arrowhead regularly informed of the status and progress of any action to the extent involving a Subject Patent, shall reasonably consider Arrowhead’s comments on any such action with respect to such Subject Patent, including determination of litigation strategy and filing of material papers to the competent court.  In addition, Amgen shall provide Arrowhead with drafts of all material papers to be filed with the court to the extent directly related to the Subject Patent and shall in good faith incorporate all reasonable comments thereto by Arrowhead before filing such papers. 

10.7Parties’ Patent Rights.  If any Arrowhead Patent or Joint Patent becomes the subject of any proceeding commenced by a Third Party within the Territory in connection with an opposition, reexamination request, action for declaratory judgment, nullity action, interference, inter partes review, or other attack upon the validity, title or enforceability thereof (except insofar as such action is a counterclaim to or defense of, or accompanies a defense of, an action for infringement against a Third Party under Section 10.4, in which case the provisions of Section 10.4 

32.

. Confidential



 

shall govern), then Arrowhead shall control such defense with respect to the Arrowhead Platform Patents and Amgen shall control such defense with respect to the Arrowhead Product Patents and Joint Patents.  The defending Party shall be responsible for all costs and expenses incurred by such Party under this Section 10.7.  The defending Party shall provide to the other Party copies of any papers relating to any such opposition, reexamination request, action for declaratory judgment, nullity action, interference or other attack upon any Arrowhead Platform Patents, Arrowhead Product Patents or Joint Patents, as applicable, reasonably in advance of their being filed or promptly upon their being received, including draft filings reasonably in advance of their being filed so that the other Party can comment and provide input with respect to such draft filings.  The defending Party agrees to discuss and consider in good faith any changes reasonably requested by the other Party to such papers, including draft filings, promptly upon their being received, toward the objective of optimizing overall patent protection for Licensed Compounds or the Licensed Product.  The defending Party shall permit the other Party to participate in the proceeding for an Arrowhead Platform Patent, Arrowhead Product Patent or Joint Patent, as applicable, to the extent permissible under applicable Laws, and to be represented by its own counsel in such proceeding, at such other Party’s expense.  If the defending Party decides that it does not wish to defend against such action, then the other Party shall have a backup right to assume defense of such Third Party action at its own expense.  Any awards or amounts received in defending any such Third Party action shall be allocated between the Parties as provided in Section 10.4(d).

10.8Patent Term Extension.  In the event Amgen desires to seek a patent term extension (including any pediatric exclusivity extensions as may be available) or supplemental protection certificate or their equivalents in any country for any Arrowhead Product Patent or Joint Patent, then the Parties shall meet and discuss such request in good faith, provided that Amgen shall have the final decision-making authority with respect thereto. In the event Amgen desires to seek any of the foregoing extensions for any Arrowhead Platform Patent, then the Parties shall meet and discuss such request in good faith and Arrowhead will not unreasonably withhold consent to such extension, provided that it shall not be unreasonable for Arrowhead to withhold its consent if such extension would materially adversely affect such Arrowhead Platform Patent or Arrowhead’s or its licensee’s development or commercialization of compounds covered by such Arrowhead Platform Patent.

10.9Regulatory Data Protection.  To the extent required by or permitted by Law, Amgen will, at its sole discretion, decide whether to list with the applicable Regulatory Authorities during the Term any applicable Arrowhead Product Patents claiming any Licensed Compound or Licensed Product that Amgen intends to, or has begun to, Commercialize, and that has become the subject of a Regulatory Approval Application submitted to FDA.  In the event Amgen desires to include in such listing any Arrowhead Platform Patent, then the Parties shall meet and discuss such request in good faith and Arrowhead will not unreasonably withhold consent to such listing, provided that it shall not be unreasonable for Arrowhead to withhold its consent if such extension would materially adversely affect such Arrowhead Platform Patent.  Such listings may include all so called “Orange Book” listings required under the Hatch-Waxman Act or listing of Patents as provided in the patent dispute resolution procedures of the Biologics Price Competition and Innovation Act of 2009 or under 42 U.S.C. § 262(l) or similar provisions in the Territory during the Term.  Prior to such decision on listings, the Parties will meet to evaluate and identify all applicable Patents to be listed and Amgen shall reasonably incorporate and address suggestions provided by Arrowhead as to the listing or non-listing of any applicable Patents.

INDEMNIFICATION

12.1Indemnification by Arrowhead.  Arrowhead shall defend, indemnify, and hold Amgen and its Affiliates and their respective officers, directors, employees, and agents (the “Amgen Indemnitees”) harmless from and against any and all Third Party claims, suits, proceedings, damages, expenses (including court costs and reasonable attorneys’ fees and expenses) and recoveries (collectively, “Claims”) to the extent that such Claims arise out of, are based on, or result from (a) the breach of any of Arrowhead’s obligations under this Agreement, including Arrowhead’s representations, warranties, and covenants set forth herein, (b) the performance by or on behalf of Arrowhead or its Affiliates or licensees of Arrowhead’s obligations under this Agreement or the development, manufacture, or commercialization by Arrowhead, its Affiliates or licensees (other than Amgen, its Affiliates or Sublicensees) of products containing RNAi Molecules solely to the extent such Claim is based on the use of the Arrowhead Licensed Technology (excluding in all cases Claims covered by the scope of 12.2) by Arrowhead, its Affiliates or licensees (other than Amgen, its Affiliates or Sublicensees) in connection with such development, manufacture or commercialization by such parties of such products, or (c) the willful misconduct or negligent acts of Arrowhead or its Affiliates in performing under this Agreement.  The foregoing indemnity obligation shall not apply to the extent that (i) the Amgen Indemnitees fail to comply with the indemnification procedures set forth in Section 12.3 and Arrowhead’s 

37.

. Confidential



 

defense of the relevant Claims is actually prejudiced by such failure, or (ii) any Claim arises from, is based on, or results from any activity set forth in Section 12.2(b) or 12.2(c) for which Amgen is obligated to indemnify the Arrowhead Indemnitees under Section 12.2.

12.2Indemnification by Amgen.  Amgen shall defend, indemnify, and hold Arrowhead and its Affiliates and their respective officers, directors, employees, and agents (the “Arrowhead Indemnitees”) harmless from and against any and all Claims to the extent that such Claims arise out of, are based on, or result from (a) the Development, Manufacture or Commercialization of Licensed Compounds or the Licensed Products by or on behalf of Amgen or its Affiliates or Sublicensees, including Claims based upon product liability and patent infringement, (b) the breach of any of Amgen’s obligations under this Agreement, including Amgen’s representations, warranties, and covenants set forth herein, (c) the willful misconduct or negligent acts of Amgen or its Affiliates in performing under this Agreement, or (d) the infringement of any Third Party Patent or misappropriation of any Third Party Information, to the extent that such infringement or misappropriation is attributable directly to any Collaboration Target (including any use thereof) as a result of Arrowhead or any of its Affiliates performing activities in accordance with Amgen’s direction pursuant to the Research Program (it being understood that the foregoing clause (d) shall only apply to the extent Amgen dictates a particular way to perform the activities or the activities are performed in a customary manner and without knowledge of any infringement or misappropriation by Arrowhead and its Affiliates).  The foregoing indemnity obligation shall not apply to the extent that (i) the Arrowhead Indemnitees fail to comply with the indemnification procedures set forth in Section 12.3 and Amgen’s defense of the relevant Claims is actually prejudiced by such failure, or (ii) any Claim arises from, is based on, or results from any activity set forth in Section 12.1(b) or 12.1(c) for which Arrowhead is obligated to indemnify the Amgen Indemnitees under Section 12.1. 

12.3Indemnification Procedures.  The Party claiming indemnity under this Article 12 (the “Indemnified Party”) shall give written notice to the Party from whom indemnity is being sought (the “Indemnifying Party”) promptly after learning of such Claim.  The Indemnified Party shall provide the Indemnifying Party with reasonable assistance, at the Indemnifying Party’s expense, in connection with the defense of the Claim for which indemnity is being sought and, if the Indemnifying Party has failed to assume defense of such Claim and the Indemnified Party has assumed and is conducting the defense of the Claim, the Indemnifying Party shall provide the Indemnified Party with reasonable assistance, at the Indemnifying Party’s expense, in connection with the defense of the Claim for which the indemnity is being sought.  The Indemnified Party may participate in and monitor such defense with counsel of its own choosing at its sole expense; provided, however, the Indemnifying Party shall have the right to assume and conduct the defense of the Claim with counsel of its choice.  The Indemnifying Party shall not settle any Claim without the prior written consent of the Indemnified Party, not to be unreasonably withheld, conditioned or delayed.  For clarity, the Indemnified Party may freely withhold its consent to a settlement of a claim with respect to Claims if (i) such settlement does not include a complete release from liability of the Indemnified Party or if such settlement would involve undertaking an obligation (including the payment of money by an Indemnified Party), (ii) would bind or impair the Indemnified Party or (iii) includes any admission of wrongdoing or that any intellectual property or proprietary right of the Indemnified Party or this Agreement is invalid, narrowed in scope or unenforceable.  So long as the Indemnifying Party is actively defending the Claim in good faith, the Indemnified Party shall not settle or compromise any such Claim without the prior written consent of the 

38.

Indemnifying Party.  If the Indemnifying Party does not assume and conduct the defense of the Claim as provided above, (a) the Indemnified Party may defend against, consent to the entry of any judgment, or enter into any settlement with respect to such Claim in any manner the Indemnified Party may deem reasonably appropriate (and the Indemnified Party need not consult with, or obtain any consent from, the Indemnifying Party in connection therewith), and (b) the Indemnifying Party shall remain responsible to indemnify the Indemnified Party as provided in this Article 12.  

12.4Limitation of Liability.  NEITHER PARTY SHALL BE LIABLE TO THE OTHER FOR ANY SPECIAL, CONSEQUENTIAL, INCIDENTAL, PUNITIVE, OR INDIRECT DAMAGES ARISING FROM OR RELATING TO ANY BREACH OF THIS AGREEMENT, REGARDLESS OF ANY NOTICE OF THE POSSIBILITY OF SUCH DAMAGES.  NOTWITHSTANDING THE FOREGOING, NOTHING IN THIS SECTION 12.4 IS INTENDED TO OR SHALL LIMIT OR RESTRICT THE INDEMNIFICATION RIGHTS OR OBLIGATIONS OF ANY PARTY UNDER SECTION 12.1 OR 12.2 WITH RESPECT TO THIRD PARTY CLAIMS, OR DAMAGES AVAILABLE FOR A PARTY’S BREACH OF CONFIDENTIALITY OBLIGATIONS IN ARTICLE 13 OR ITS OBLIGATIONS IN SECTIONS 3.1 AND 3.3.

12.5Insurance.  Each Party shall procure and maintain insurance (or self-insure sufficiently to provide materially the same level and type of protection) adequate to cover its obligations hereunder during the Term and consistent with normal business practices of companies similarly situated.  It is understood that such insurance shall not be construed to create a limit of either Party’s liability with respect to its indemnification obligations under this Article 12.  Each Party shall provide the other Party with written evidence of such insurance upon request.  

Article 13
CONFIDENTIALITY

13.1Confidentiality.  Each Party agrees that, during the Term and for a period of [***] years thereafter, it shall keep confidential and shall not publish or otherwise disclose and shall not use for any purpose other than as provided for in this Agreement (which includes the exercise of any rights or the performance of any obligations hereunder) any Confidential Information furnished to it by the other Party pursuant to this Agreement, except to the extent expressly authorized by this Agreement or otherwise agreed in writing by the Parties.  Each Party will use at least the same standard of care as it uses to protect proprietary or confidential information of its own (but no less than reasonable care) to ensure that its employees, agents, consultants, contractors and other representatives do not disclose or make any unauthorized use of the Confidential Information of the other Party.  Each Party will promptly notify the other upon discovery of any unauthorized use or disclosure of the Confidential Information of the other Party.  The foregoing confidentiality and non-use obligations shall not apply to any portion of the other Party’s Confidential Information that:

(a)was already known to the receiving Party or any of its Affiliates, other than by previous disclosure of the disclosing Party or any of its Affiliates, at the time of disclosure by the other Party;

(c)becomes generally available to the public or otherwise part of the public domain after its disclosure and other than through any act or omission of the receiving Party in breach of this Agreement;

(d)was disclosed to the receiving Party or any of its Affiliates on a non-confidential basis by a Third Party who is not known by the Receiving Party after due inquiry to be subject to an obligation of confidentiality to the other Party; or

(e)was independently discovered or developed by the employees, subcontractors, consultants or agents of the receiving Party or any of its Affiliates without use of the other Party’s Confidential Information, as evidenced by a contemporaneous writing.

13.2Authorized Disclosure.  Notwithstanding the obligations set forth in Section 13.1, a Party may disclose the other Party’s Confidential Information and the terms of this Agreement to the extent:

(a)such disclosure is reasonably necessary (i) to comply with the requirements of Regulatory Authorities with respect to obtaining and maintaining Regulatory Approval of a Licensed Product; or (ii) for prosecuting or defending litigation as contemplated by this Agreement;

(b)such disclosure is reasonably necessary to its employees, agents, consultants, contractors, licensees or sublicensees on a need-to-know basis for the sole purpose of performing its obligations or exercising its rights under this Agreement; provided that in each case, the disclosees are bound by written obligations of confidentiality and non-use consistent with those contained in this Agreement; 

(c)such disclosure is reasonably necessary to any bona fide potential or actual investor, acquirer, merger partner, licensee, sublicensee, or other financial or commercial partner for the sole purpose of evaluating an actual or potential investment, acquisition or other business relationship; provided that in connection with such disclosure, such Party shall inform each disclosee of the confidential nature of such Confidential Information and, in each case, the disclosees are bound by written obligations of confidentiality and non-use consistent with those contained in this Agreement; and provided further, that no financial terms shall be disclosed to any such potential investor, acquirer or partner if it has a competing product to any Licensed Compound or Licensed Product; or

(d)such disclosure is reasonably necessary to comply with applicable Laws, including regulations promulgated by applicable security exchanges, court order, administrative subpoena or order.

Notwithstanding the foregoing, in the event a Party is required to make a disclosure of the other Party’s Confidential Information pursuant to Section 13.2(a) or 13.2(d), such Party shall promptly notify the other Party of such required disclosure and shall use reasonable efforts to obtain, or to assist the other Party in obtaining, a protective order preventing or limiting the required disclosure.

Any information disclosed pursuant to Section 13.2(a) through Section 13.2(d) shall still be deemed Confidential Information and subject to the restrictions set forth in this Agreement, including the foregoing provisions of Article 13.

13.3Technical Publication.  During the Term, neither Party may publish peer reviewed manuscripts, or give other forms of public disclosure such as abstracts and presentations, of results of studies carried out under this Agreement, without the opportunity for prior review by the other Party, and subject to this Section 13.3, below, except to the extent required by applicable Laws; provided, however, that Amgen will have the sole right (without Arrowhead’s consent) to publish and make scientific presentations with respect to Licensed Compounds or Licensed Products or make other public disclosures regarding any such Licensed Compounds or Licensed Products, and Arrowhead will not do so without Amgen’s prior written consent, except as required by applicable Law.  No publication shall include the other Party’s Confidential Information without the prior written consent of such other Party.  A Party seeking publication shall provide the other Party the opportunity to review and comment on any proposed publication (or where a copy of such publication or presentation is not available at such time, a draft or outline of such publication or description of such presentation) that relates to an RNAi Molecule directed to the Collaboration Target or any Licensed Compound or Licensed Product, at least [***] days prior to its intended submission for publication.  The other Party shall provide the Party seeking publication with its comments in writing, if any, as promptly as practicable after receipt of such proposed publication.  The Party seeking publication shall consider in good faith any comments thereto provided by the other Party and shall comply with the other Party’s request to remove any and all of such other Party’s Confidential Information from the proposed publication.  In addition, the Party seeking publication shall delay the submission for a period up to [***] days in the event that the other Party can demonstrate reasonable need for such delay, including the preparation and filing of a patent application (or, in the case that a Party has a compelling business justification, for a longer period reasonably selected by that Party).  Each Party agrees to acknowledge the contributions of the other Party and its employees in all publications as scientifically appropriate.

13.4Publicity; Terms of this Agreement.

(a)The Parties agree that the terms of this Agreement are the Confidential Information of both Parties, subject to the special authorized disclosure provisions set forth in this Section 13.4.

(b)Public announcement of the execution of this Agreement shall be made substantially in the form of the press release attached hereto as Exhibit F, on or promptly after the Effective Date.

(c)After release of such press release, if either Party desires to make a public announcement concerning the terms of this Agreement, such Party shall give reasonable prior advance notice of the proposed text of such announcement to the other Party for its prior review and approval (except as otherwise provided herein).  A Party commenting on such a proposed press release shall provide its comments, if any, within [***] after receiving the press release for review.  Notwithstanding the foregoing, a Party shall have the right to make a public announcement or press release announcing the achievement of each Regulatory Approval development and regulatory milestone event set forth in Section 9.5 (excluding, for clarity, the Initiation of Phase 3 

41.

. Confidential



 

Clinical Trial milestones) as it is achieved either (i) with the consent of the other Party (not to be unreasonably withheld); (ii) where required by applicable Laws or regulations promulgated by an applicable security exchange; or (iii) as permitted under Section 13.2.  Except as provided in this subsection (c) or permitted under Section 13.2, no press release shall include the other Party’s Confidential Information without the prior written consent of such other Party.  In relation to the other Party’s review of such an announcement, such other Party may make specific, reasonable comments on such proposed press release within the prescribed time for commentary.  Neither Party shall be required to seek the permission of the other Party to repeat any information regarding the terms of this Agreement that has already been publicly disclosed by such Party, or by the other Party, in accordance with this Section 13.4, provided such information remains accurate as of such time.

(d)The Parties acknowledge that either or both Parties may be obligated to file a copy of this Agreement and summaries of the terms hereof with the U.S. Securities and Exchange Commission or other Governmental Authority as reasonably required to comply with applicable Laws or the rules of a nationally-recognized securities exchange.  Each Party shall be entitled to make such filings, provided that it requests confidential treatment of the commercial terms, sensitive technical terms and other terms of this Agreement that a Party reasonably deems sensitive or competitive to the extent such confidential treatment is reasonably available to such Party; provided that the foregoing obligation to request confidential treatment shall not apply with respect to any disclosure of this Agreement by either Party to the U.S. Internal Revenue Service or similar Governmental Authority outside the U.S.  In the event of any such filing, each Party will provide the other Party with a copy of this Agreement and related filings marked to show provisions for which such Party intends to seek confidential treatment and shall reasonably consider and incorporate the other Party’s comments thereon to the extent consistent with the legal requirements and the rules of any nationally recognized securities exchange, with respect to the filing Party, governing disclosure of material agreements and material information to be publicly filed.

13.5Equitable Relief.  Each Party acknowledges that its breach of this Article 13 may cause irreparable harm to the other Party, which cannot be reasonably or adequately compensated in damages in an action at law.  By reasons thereof, each Party agrees that the other Party shall be entitled, in addition to any other remedies it may have under this Agreement or otherwise, to seek preliminary and permanent injunctive and other equitable relief to prevent or curtail any actual or threatened breach of the obligations relating to Confidential Information set forth in this Article 13 by the other Party.

13.6Attorney-Client Privilege.  Neither Party is waiving, nor will be deemed to have waived or diminished, any of its attorney work product protections, attorney-client privileges or similar protections and privileges recognized under the applicable law of any jurisdiction as a result of disclosing information pursuant to this Agreement, or any of its Confidential Information (including Confidential Information related to pending or threatened litigation) to the receiving Party, regardless of whether the disclosing Party has asserted, or is or may be entitled to assert, such privileges and protections.  The Parties may become joint defendants in proceedings to which the information covered by such protections and privileges relates and may determine that they share a common legal interest in disclosure between them that is subject to such privileges and protections, and in such event, may enter into a joint defense agreement setting forth, among other things, the foregoing principles, but are not obligated to do so.

If the Parties reasonably and in good faith disagree as to whether there has been a material breach, the Party that disputes that there has been a material breach may contest the allegation in accordance with Article 15.  It is understood and acknowledged that, during the pendency of such a Dispute, the Cure Period shall be extended by the period of time of such pendency, all of the terms and conditions of this Agreement shall remain in effect, and the Parties shall continue to perform all of their respective obligations under this Agreement; provided that for any Dispute over payment, such tolling of the Cure Period will only apply with respect to payment of the disputed amounts and not with respect to any undisputed amounts.  Nothing in this Section 14.3 shall limit a Party’s ability to seek remedies available under this Agreement in law or equity.

Notwithstanding anything to the contrary, the following provisions shall survive any expiration or termination of this Agreement: Article 1, Article 12, Article 13, (for the period set forth in Section 13.1), and Article 16 (except for Section 16.6(b) and 16.6(c)) and Sections 2.7, 2.9, 2.11, 3.1, 3.3, 3.4, 9.5, 9.6, 9.7, 9.9, 9.10 (each such listed section in Article 9 to the extent applicable to payments for milestone events or sales of Licensed Products that occurred prior to the effective date of such termination or expiration and payable by Amgen under Article 9), 10.1, 11.5, 14.5 (as applicable), 14.6, and 14.7.

14.7No Limitation on Remedies.  Notwithstanding anything to the contrary in this Agreement, termination or expiration of this Agreement shall not relieve the Parties of any liability or obligation which accrued hereunder prior to the effective date of such termination or expiration nor prejudice either Party’s right to obtain performance of any obligation.

MISCELLANEOUS

16.1English Language; Governing Law; Jurisdiction.  This Agreement was prepared in the English language, which language shall govern the interpretation of, and any dispute regarding, the terms of this Agreement.  This Agreement and all disputes arising out of or related to this Agreement or any breach hereof shall be governed by and construed under the laws of the State of New York, U.S., without giving effect to any choice of law principles that would require the application of the laws of a different jurisdiction.  Each of the Parties hereby irrevocably and unconditionally consents to submit to the exclusive jurisdiction of the federal and state courts located in the State of New York for any matter arising out of or relating to this Agreement and the transactions contemplated hereby, and agrees not to commence any litigation relating thereto except in such courts.  Each of the Parties hereby irrevocably and unconditionally waives any objection to the laying of venue of any matter arising out of this Agreement or the transactions contemplated hereby in the federal and state courts located in the City and State of New York and hereby further irrevocably and unconditionally waives and agrees not to plead or claim in any such court that any such matter brought in any such court has been brought in an inconvenient forum.  The Parties agree that a final judgment in any such matter shall be conclusive and may be enforced in other jurisdictions by suits on the judgment or in any other manner provided by law.  

16.2Entire Agreement; Amendment.  This Agreement, including the Exhibits hereto, and the Stock Purchase Agreement, set forth the complete, final and exclusive agreement and all the covenants, promises, agreements, warranties, representations, conditions and understandings between the Parties with respect to the subject matter hereof and supersedes, as of the Effective Date, all prior and contemporaneous agreements and understandings between the Parties with respect to the subject matter hereof, including the Confidentiality Agreement.

alteration, amendment, change or addition to this Agreement shall be binding upon the Parties unless reduced to writing and signed by an authorized officer of each Party. 

16.3Force Majeure.  Both Parties shall be excused from the performance of their obligations under this Agreement to the extent that such performance is prevented by force majeure and the nonperforming Party promptly provides notice of the prevention to the other Party.  Such excuse shall be continued so long as the condition constituting force majeure continues and the nonperforming Party takes reasonable efforts to remove the condition.  For purposes of this Agreement, force majeure shall include conditions beyond the control of the Parties, including an act of God, war, terrorist act, labor strike or lock-out, epidemic, and fire, earthquake, storm, release of radioactive material into the environment, or like catastrophe.  Notwithstanding the foregoing, a Party shall not be excused from making payments owed hereunder because of a force majeure affecting such Party.  If a force majeure persists for more than ninety (90) days, then the Parties will discuss in good faith the modification of the Parties’ obligations under this Agreement in order to mitigate the delays caused by such force majeure.

16.4Notices.  Any notice required or permitted to be given under this Agreement shall be in writing, shall specifically refer to this Agreement, and shall be addressed to the appropriate Party at the address specified below or such other address as may be specified by such Party in writing in accordance with this Section 16.4, and shall be deemed to have been given for all purposes (a) when received, if hand-delivered or sent by confirmed facsimile or a reputable courier service, or (b) five (5) Business Days after mailing, if mailed by first class certified or registered airmail, postage prepaid, return receipt requested.

16.5No Strict Construction; Headings.  This Agreement has been prepared jointly by the Parties and shall not be strictly construed against either Party.  Ambiguities, if any, in this Agreement shall not be construed against any Party, irrespective of which Party may be deemed to have authored the ambiguous provision.  The headings of each Article and Section in this Agreement have been inserted for convenience of reference only and are not intended to limit or expand on the meaning of the language contained in the particular Article or Section.  The use of any gender shall be applicable to all genders.  The word “or” is used in the inclusive sense (and/or) unless the context dictates otherwise because the subjects of the conjunction are mutually exclusive.  The term “including” means “including without limitation,” without limiting the generality of any description preceding such term.  The term “shall” means “will”.

16.6Assignment.  

(a)Neither Party may assign or transfer this Agreement or any rights or obligations hereunder without the prior written consent of the other Party, except that a Party may make such an assignment or transfer without the other Party’s consent (i) to an Affiliate (for so long as such entity remains an Affiliate) or (ii) only of the entire Agreement (not just certain rights or obligations) to a Third Party acquiror or its Affiliate in connection with a Change of Control of such Party (such Third Party, an “Acquiror”).  Any successor or assignee of rights or obligations permitted hereunder shall, in writing to the other Party, expressly assume performance of such rights or obligations.  Any permitted assignment shall be binding on the successors of the assigning Party.  Any assignment or attempted assignment by either Party in violation of the terms of this Section 16.6 shall be null, void and of no legal effect.

(b)In the event of any such assignment under Section 16.6(a)(ii) in connection with a Change of Control of Arrowhead, all intellectual property rights (including any Information or Patents) owned or otherwise Controlled by the Acquiror or its Affiliates (except for Arrowhead, if remaining as a separate Affiliate or otherwise the successor entity thereto) shall be excluded from the licenses granted to Amgen under this Agreement and the Arrowhead Research IP and Arrowhead Licensed Technology (including in each case any such intellectual property rights (including any Information or Patents) owned or otherwise Controlled by such Acquiror as of the date of consummation of such transaction), except for any Invention generated by the Acquiror or its Affiliates in performing any activity under this Agreement.  Notwithstanding the foregoing, in the case of either of (x) a Change of Control of Arrowhead or (y) the acquisition by Arrowhead of all or substantially all of the business of a Third Party (together with any entities that were Affiliates of such Third Party immediately prior to such acquisition, a “Acquiree”), whether by merger, consolidation, divesture, restructure, sale of stock, sale of assets or otherwise (an “Acquisition”), to the extent that any Third Party acquirer in such Change of Control or such Acquiree, as applicable, owns any Blocking Patents relative to a Licensed Compound or a Licensed Product, Arrowhead shall and hereby does grant to Amgen a non-exclusive license, for 

47.

. Confidential



 

no additional consideration (provided, however, that in the event that Arrowhead would be obligated to make any payments to a Third Party in connection with the grant of the foregoing license to any Blocking Patents, then unless Amgen agrees to assume such payment obligations, such license grant will exclude a license under the applicable Blocking Patents), until the expiration of the last to expire of such Blocking Patents, on a country-by-country basis, or termination of this Agreement relative to such Licensed Compound or Licensed Product, whichever comes first, provided that at the time of such transaction contemplated by (x) or (y), such non-exclusive license rights are available for such grant and have not been exclusively licensed to any Third Party.

(c)In the event of any such assignment under Section 16.6(a)(ii) in connection with a Change of Control of Amgen, all intellectual property rights (including any Information or Patents) owned or otherwise Controlled by the Acquiror or its Affiliates (except for Amgen, if remaining as a separate Affiliate or otherwise the successor entity thereto) shall be excluded from the licenses granted to Arrowhead under this Agreement (including any such intellectual property rights (including any Information or Patents) owned or otherwise Controlled by such Acquiror as of the date of consummation of such transaction), except for any Invention generated by the Acquiror or its Affiliates in performing any activity under this Agreement.

16.7Further Actions.  Each Party agrees to execute, acknowledge and deliver such further instruments, and to do all such other acts, as may be necessary or appropriate in order to carry out the purposes and intent of this Agreement.

16.8Rights in Bankruptcy.  All rights and licenses granted under or pursuant to this Agreement by Arrowhead are, and shall otherwise be deemed to be, for purposes of Section 365(n) of the Bankruptcy Code, licenses of rights to "intellectual property" as defined under Section 101 of the Bankruptcy Code.  The Parties agree that Amgen, as licensee of such rights under this Agreement, shall retain and may fully exercise all of its rights and elections under the Bankruptcy Code including without limitation Amgen's right to retain all licenses to Arrowhead Licensed Technology granted herein.  Without limiting the generality of the foregoing, the Parties intend and agree that any sale of Arrowhead's assets under Section 363 of the Bankruptcy Code shall be subject to Amgen’s rights under Section 365(n), that Amgen cannot be compelled to accept a money satisfaction of its interests in Arrowhead Licensed Technology, and that any such sale therefore may not be made to a purchaser "free and clear" of Amgen's license rights without the consent of Amgen.  The Parties further agree that, in the event of the commencement of a bankruptcy proceeding by or against Arrowhead under the Bankruptcy Code, Amgen shall be entitled to a complete duplicate of (or complete access to, as appropriate) any such intellectual property and all embodiments of such intellectual property, and the same, if not already in its possession, shall be promptly delivered to them (i) upon any such commencement of a bankruptcy proceeding upon its written request therefor, unless Arrowhead elects to continue to perform all of its obligations under this Agreement, or (ii) if not delivered under (i) above, following the rejection of this Agreement by or on behalf of Arrowhead upon written request therefor by Amgen. (The Parties acknowledge and agree that "embodiments" of intellectual property within the meaning of Section 365(n) include without limitation laboratory notebooks, RNAi Molecules, inventory, research studies, data, and regulatory approvals).  Additionally, if (a) a case under the Bankruptcy Code is commenced by or against Arrowhead, (b) this Agreement is rejected as provided in the Bankruptcy Code, and (c) Amgen elects to retain its rights hereunder as provided in Section 365(n)

of the Bankruptcy Code, Arrowhead (in any capacity, including debtor-in-possession) and its successors and assigns (including a trustee) shall not interfere with Amgen's rights under this Agreement to Arrowhead Licensed Technology (including such embodiments), including any right to obtain such Arrowhead Licensed Technology (or such embodiments) from another entity, to the extent provided in Section 365(n) of the Bankruptcy Code.  All rights, powers and remedies of Amgen provided herein are in addition to and not in substitution for any and all other rights, powers and remedies now or hereafter existing at law or in equity (including the Bankruptcy Code) in the event of the commencement of a case under the Bankruptcy Code with respect to Arrowhead. The Parties agree that they intend the following rights to extend to the maximum extent permitted by law, and to be enforceable under Section 365(n) of the Bankruptcy Code: (I) the right of access to any Arrowhead Licensed Technology (including all embodiments thereof) of Arrowhead, or any Third Party with whom Arrowhead contracts to perform an obligation of Arrowhead under this Agreement, and, in the case of the Third Party, which is necessary for the development, manufacture, supply, commercialization, sale, import or export of Licensed Compounds or Licensed Products, in any case solely as provided under this Agreement; and (II) the right to contract directly with any Third Party to complete the same.

16.9Severability.  If any one or more of the provisions of this Agreement is held to be invalid or unenforceable by any court of competent jurisdiction from which no appeal can be or is taken, the provision shall be considered severed from this Agreement and shall not serve to invalidate any remaining provisions hereof.  The Parties shall make a good faith effort to replace any invalid or unenforceable provision with a valid and enforceable one such that the objectives contemplated by the Parties when entering this Agreement may be realized.

16.10No Waiver.  Any delay in enforcing a Party’s rights under this Agreement or any waiver as to a particular default or other matter shall not constitute a waiver of such Party’s rights to the future enforcement of its rights under this Agreement, except with respect to an express written and signed waiver relating to a particular matter for a particular period of time.

16.11Independent Contractors.  Each Party shall act solely as an independent contractor, and nothing in this Agreement shall be construed to give either Party the power or authority to act for, bind, or commit the other Party in any way.  Nothing herein shall be construed to create the relationship of partners, principal and agent, or joint-venture partners between the Parties.

16.12No Third Party Beneficiaries.  This Agreement is neither expressly nor impliedly made for the benefit of any party other than the Parties and their successors and permitted assigns, except for the persons expressly entitled to indemnification as provided in Article 12 and only in accordance with the terms of such Article 12

16.13Counterparts; Electronic Delivery.  This Agreement may be executed in counterparts, by original, facsimile or PDF signature, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument.  Signatures to this Agreement transmitted by facsimile, by email in “portable document format” (“.pdf”), or by any
